PbSe Nanowires in Non-Coordinating Solvent

摘要

A PbSe nanowire having an aspect ratio of about 100:1 and having a diameter of less than 20 nm. A PbSe nanowire produced by the process comprising reacting PbO with oleic acid in 1-octadecene or other non-coordinating solvent and producing Pb oleate in a flask, heating the Pb oleate to between 225 and 275 C under inert gas, injecting a first solution of Se dissolved in trialkylphosphine into the flask and producing a second solution, heating the second solution, maintaining the temperature 200 C in the flask, and resulting in PbSe nanowires.
